If you weren't having any issues with speed and they've progressively gotten worse, I'd look at dedup. If you're using dedup, you better make sure you've got 2.5GB RAM for every TB of unique data you have, otherwise you'll be swapping your dedup tables constantly and your read/write performance is

[OpenIndiana-discuss] SMF svcadm restart-or-clear-or-start action

I am going to offer to obvious advice... How full is your pool? Zpool performance degrades as the pool fills up and the tools don't tell you how close you are to the cliff -- you find the cliff on your own by falling off of it. As a rule of thumb, I keep production system less than 70%
